To all whom it may concern: 1

Be it known that we, WILLIAM N. ONEILL and HARRY PARKER, J r;, citizens of the United States, residing at Columbus, in the county'of Franklin and Stateof Ohio, have invented new and useful Improvements in Yarn-Dampening Devices, of which the following is a specification This invention relates to a device for dampening or lubricating yarns or threads on the feed of the same to a knitting machine in order to insure the proper looping of the threads and diminish their liability to break close proximity to the knitting machine without liability of the latter being injured or affected by moisture therefrom, which is adapted for the ready connection of the thread therewith and its disconnection therefrom, and which provides for the through the float feed device and yarn guideassociated therewith.

In carrying our inventlon into practice,

we provide a tank or reservoir lto contain the.

dampening or lubricating liquid, which may be of any desired character. The reservoir is preferably of oblong rectangular form and provided at one end with hooks 2 or other suitablemeans for attaching it to the" knitting machine or any suitable support in proximity thereto. .At thesaid end of the reservoir is also arranged an eye or guide- 3 for the yarn or thread, which is employed when the thread spool is arranged at a higher level than the reservoir. Arranged at the opposite end of the tank is a transverse bearing rib or wiper 4 over which the dampened thread passes to the knitting machine, and a pair of upright supporting pins or arms 5 having pointed free ends, which pins may be employed forsupporting a fabric wiper or absorbent strip 6 adapted for operation in conjunction with said wiper rib to take up and absorb from the yarn any excess moisture which may be present therein. The absorbent strip is supported, as shown, by simply impaling it upon the pins, whereby it may be renewed and replaced by a new strip whenever necessary in a ready and convenient manner. By the use ofthese wipers in conjunction with the float feed dampeningdevice, hereinafter described, the yarn will be dam ened only to bricating liquid. This body is preferably composed of a top plate. or member 8 having" a depending tubular extension 9-and a bottom plate or member 10 secured to the top plate and surrounding said tubular extension. The top plate and its extension are preferably formed in whole or part'of a non-absorbent, moisture-shedding material,

-while thebottorn plate is composed of cork 'or other suitable material having buoyant properties sufiici ent to support the body 'flin the liquid so that the upper surface 'of the top'platewill be leveled or substantially a; suflicient degree to make it readily pliable so with the surface of the liquid. The bore 11 or the tubular extension 9 forms a passage for the feed of the liquid to a well gutter or channel 12' formed in the upper surface, of the top plate, and the side walls of said bore and gutter are provided with guide and retaining grooves 13. Extending transversely above the forward end of the gutter is a transverse bar or rib 14 under which the moistened thread preliminarily passes, which bar or rib sustains the thread :above the level of the top of the float and operates as a primary wiper. Carried by the float is a thread guide preferably formed of a single piece of spring wire and comberetracted or drawn inwardly toward each other to free them from engagement with the grooves, allowing the guide member as a whole to be detached or adjusted verticallyto raise orv lower the eye 18 so that the feeding thread may be caused to dip to a greater or less extent in the liquid'con tained' in the gutter, whereby the amount of moisture taken up by the thread may be varied and controlled. The forward end of the float isprovided with suitable stop pins or projections 20 toengage the front Wall of the tank and thus limit the forward movement of the float under the pull of the feeding thread. a

In operation, it will be apparent that the thread may be'engaged with and disengaged from the eye or passage by simply sliding it downwardly or upwardly between the arms of the guide member, and that in its passage through the dampening device it will take up more or less moisture from the gutter or well according to the position of adjustment ofthe eye, whereby provision is made for-dampening the thread to approxi- Jnately the exact degree required and for varying the ameunt, of saturation according. to the character of the thread. to be treated.

' If, however, too much moisture should be taken up by the thread, all of the excess,

moisture will be expressed and absorbed by to maintain the same amount of liquid at' gutter, and that agitation all times in the ofthe contained liquid will be avoided, thus preventing all loss or waste from the splashingof the liquid over the sides of the tank, such as occurs in dampening devices of the character employing dampening rollers.

injury to the yarn and knitting mechanism from the dampening liquid avoided.

4 Having thus described the invention, we claim z- .1. A thread moistening or lubricating deyice comprising a liquid reservoir, and a float arranged within the reservoir to rise and fall with the liquid. therein, said float being provided with means for guiding the thread and bringing the same into contact with a' portion of the liquid.

2. K thread moistenlng or lubricating devlce comprlslng a llquid reservoir, a float arranged within the reservoir and provided with a Well, and a thread guide arranged to conduct the'thread in contact with the liquid contained in the well.

3. 'A thread moistening or lubricating device comprising a liquid reservoir, a float arranged within the reservoir, and provided 3 with a well communicating with the body of liquid below the top thereof, and a thread guide arranged to conduct the thread across the top of the well and into contact with the liquid contained therein.

4. A thread-moistening or lubricating device comprising a liquid reservoir, a float arranged within the reservoir and provided with a well, and a thread guide adjustable with relation tothe surface of the'liquid 1 contained in the well.

J5. A thread moistening or lubricating devlce comprising a liquid reservoir; a float arwell in .its top and a feed passage leading therefrom for the feed of the liquid thereto,

and a thread guide having a split eye for 95 ranged within the reservoir and having a 6. A thread moistening or lubricating de- I vice comprising a reseryoir, a float arranged wlthin the reservoir and provided with a well communicating with thebody of liquid in the reservoir, a thread guide carried by the float, and means for relieving the thread of excess liquid. i y

7. A thread moistening or lubricating device comprising a reservoir, a float arranged Within the reservoir and provided with a well communicating with the body of liquid 1n the reservoir, thread guiding means carried by the float, a wiper upon the reservoir in the path of movement of the moistened thread, and meansfupon the reservoir for supportlng an absorbent fabric for contact with the moistened thread.

vice comprising a reservoir, a floatv arranged wlthln the reservoir and provided in its upper surfacewith a well and having a passage leading downward therefrom for the feed o'f-the liquid thereto, and a thread ,gulde detachably and adjustably supported Cleanliness of operation is thus insured and 1 y the float and. having a spliteye for the passage of the thread across the surface of thewell. I q I 9. A thread moistening-or lflbricating devlce comprisin a liquid reservoir, a float arranged therein and. having a well in its upper face and a feed passage leading downward. therefrom for the supply of liquid j '8. A. thread moistening or lubricating dethereto from the reservoir, and a thread guide having spring jaws to engage the wall of the well and passages, for adjustable Connection therewlth, finger pieces for detracting said jaws and cross portions forming a split. eye for the passage of the thread.

In testimony whereof we aflix our signatures in presence of two witnesses.
